My first Spyderco knife was a "Q" with the spider design on the blade and 'USA' on the handle. The clip was reversible fo a lefty. The clip holes were a little too weak to hold the clip and I lost it. Never replaced the clip or missed it. The knife did a few years of warehouse and delivery work: Sawing open large and heavy cardboard boxes, cutting plastic banding and lots of rope and tape. When I was promoted to a warehouse manager, the Q was the perfect knife to have in my dockers for many of the same tasks.
Almost 10 years later I am at a computrer company and was helping to package up some routers, well, out of storage came the Q! The skelatel leaf blade was easy to thumb for shallow cuts and slices and the serrations easily 'modified' the packing foam. All and all a great knife. I really need to send it in for a professional sharpining as they just don't make them anymore!
